Company Overview
Citadel Maritime was founded by two former Royal Marine Commando’s who had served together on Combat Operations.

After leaving the Royal Marines and working for Top-Tier Maritime Security companies each felt that there was a significant disconnect in the relationship between the Security Companies and their employees which increased risk for the Masters and Crew they protected.  Their solution was to start Citadel.  A company designed to attract the best in the industry.  This is why we focus so carefully on creating an Operational Environment where our Operators can do their best work.

Our retention rate for our Maritime Security Consultants is 93.6%.  This is amongst the highest in the industry.
